Improvement in roofing materials



UNITED STATES PATENT OFFICE.

DELAPLAIE MODANIEL, OF PHILADELPHIA, PENNSYLVANIA,

IMPROVEMENT IN ROOFINC- MATERIALS.

Specification forming part of Letters Patent No. l 64,749, dated June 22, 1875; application filed Aprn 1o, 1875. v

To all whom it may concern:

Be it known that I, DELAPLAINE McDAN- IEL, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and valuable Improvement in Roofing; and l do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part ot' this specification,

and to the letters and tigures of reference marked thereon.

Figure 1 of the drawings is a representation of my roofing material.

This invention has relation to means for preventing the sweating and leaking of metallic roofing 3 and it consists in providing the metal sheeting with a lining of paper or other brous materialm permanently attached thereto and compressed, forming a substantial rooting material capable or' being transported and handled in the improved form, as hereinafter fully shown and described. l

The object of this invention is mainly to obviate some material objections to the use of galvanized iron, common black sheet-iron, and othern`etallic substancesLv for rooting purposes. It is found, when such articles are employed without sheathing-boards, that when the atmosphere is at a higher temperature within the building than without, cou` densation will occur, and the moisture, collecting olthe under side of the sheeting, will drip down within the house, wetting whatever it comes in contact with. Moreover,

,when the jointing of the sheets isA made by plain lapping these joints are not tight, and permit leakage.

In carrying out the manufacture of my roofing material, I provide 'a roll of paper or other brous material, preferably what is known as vulcanized paper prepared by the Vulcanized Fiber Company, of Delaware. Paper is an economical material, and when prepared in a proper manner answers the purpose well.

The roll of paper is swung above the table or platform on which the sheet metal is laid. The latter is then coated with egg-albumen, white lead, orothersuitable adhesive material, which will take hold of the metal, and enough of the paper is unrolled to cover the metallic sheet on one side. Then the metal and paper are firmly pressed together to force out all airblisters and insure a thorough union, by passing a roller over them, or by passing the united sheets between pressing-rollers, or laying them under the follower of a reciprocating-press.

This improvement is especially adapted for corrugated sheet-metal roong, which is more open to the objections referred to than plain roofing, on account of the greater surface and the depending ribs from which the moisture is liable to drip upon the ceiling where it is comparatively unsupported.

The metal and lining sheets having been united and compressed together, are laid away in a position for the adhesive material to harden sufficiently to allow the combined sheet to be corrugated, if the material is desired in this form. When dried, the sheets, whether corrugated or plain, are treated in building in the same manner as the ordinary metallic sheets.

What I claim as new, and desire to secure by Letter Patent, is-

As a new article of manufacture, the rooting material consisting of the metallic sheet and iibrous-lining sheet united by suitable adhesive material under compression, substantially as specified.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two Witnesses.
